- Weight (g): 6.850,00
Bosh Rexroth R165351310 Heavy-duty Ball Runner Block FLS, Size 55, C1 Moderate preload, Accuracy class H, SS Standard seal, No initial lubrication Heavy-duty Ball Runner Block FLS, standard, steel, R1653 10
Area of application: For the most demanding rigidity requirements
Heavy-duty Ball Runner Block for heavy machine construction with extremely high load-bearing capacity
Top rigidity in all load directions
Improved rigidity under lift-off and side loading conditions due to two additional mounting screw holes at the center of the Ball Runner Block
High torque capacity
Attachments on the Ball Runner Block can be mounted from above and below
Minimum lubrication quantities thanks to innovative channel design
Smooth, quiet running thanks to optimally designed ball return and guidance
Optimized entry-zone geometry and high number of balls minimize variation in elastic deflection
Different preload classes
End-face fastening thread for all attachments
Can be used on all SNS Ball Guide Rails
Limitless interchangeability as all Ball Guide Rail versions can be combined at will with all Ball Runner Block versions
Due to the Rexroth design with four rows of balls, 2-point contact is available in all loading directions. This reduces the friction to a minimum.
Other ball rail systems with two or four rows of balls with 4-point contact have multiple friction: due to the differential slip with lateral loading and in case of comparable prestressing without the load, the gothic raceway profile causes higher friction (depending on the raceway curvature and the load, up to five times the friction coefficient). This high friction leads correspondingly to greater heat.
Seals are use to prevent dirt, chips and coolants, etc. from working their way into the inside of he Ball Runner Block, thereby preventing reductions to its service life.
Standard seal (SS)
Universal seals are fitted as standard in Rexroth Ball Runner Blocks. They have a uniform sealing effect for Ball Guide Rails with and without cover strips. Low friction and a good sealing effect have both been taken into account in the design. For applications where effective sealing is required.
Low-friction seal (LS)
For special requirements with regard to ease of movement.
Double-lip seal (DS)
For increased exposure to media
For applications in environments with fine dirt or metal particles, as well as coolants or cutting fluids. Interchangeable during servicing.
For applications in extreme environments with fine dirt or metal particles, as well as heavy use of coolants or cutting fluids. Interchangeable during servicing.
Cover plate wiper
For use in environments with coarse dirt or chips.
